Medium risk. 4 critical or high findings in Security headers and GDPR outside view.

Security score

73/100

Risk levelMedium

0–100, higher is better. How it is calculated

Diwa Mediamatik is a small Swiss technology company specializing in web design, hosting, and media services with over 30 years of experience. Their business model focuses on providing end-to-end internet presence solutions including CMS, SEO consulting, and media production primarily targeting clients in the Aargau region. The website demonstrates a solid technical foundation using modern web technologies and a proprietary CMS named Jasmin. While the site is well-structured, mobile-optimized, and includes a cookie consent mechanism, it lacks explicit security policies and terms of service. Security posture is moderate with room for improvement in headers and incident response transparency. Overall, the domain registration and business information are consistent and trustworthy, supporting a high legitimacy score.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company holds a strong local market position as a specialist in internet communication and web services in Switzerland. Their competitive advantage lies in their long-standing experience and comprehensive service offering from concept to hosting and support. The business targets small to medium enterprises and individuals requiring professional web presence solutions. Partnerships such as with Host Europe for hosting and Swiss Made Software for software quality endorsement enhance their ecosystem. The company’s growth is steady, supported by a clear branding strategy and consistent content quality.

Security posture

The website employs basic security best practices including HTTPS (assumed), email obfuscation, and cookie consent. However, it lacks visible security headers and published security or incident response policies. No vulnerability disclosure or security.txt files are present. The absence of terms of service and detailed privacy compliance statements may pose compliance risks. The support SLA indicates some operational security awareness. Overall, the security maturity is moderate but could be enhanced by implementing recommended headers, formal policies, and incident response contacts.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and HSTS to improve security posture.
  2. Publish a clear security policy and incident response contact information to enhance transparency and trust.
  3. Ensure SSL/TLS certificates are properly configured and enforced site-wide.
  4. Add accessibility improvements to meet WCAG standards for better inclusivity.
  5. Develop and publish terms of service and vulnerability disclosure policies to comply with best practices and legal requirements.

Technical notes

Notes

The website is built with standard HTML5, CSS, and JavaScript, incorporating Font Awesome icons and a custom CMS named Jasmin. Hosting is provided by Host Europe, indicating a professional hosting environment. The site uses video backgrounds and responsive design techniques for mobile optimization. SEO is addressed through meta tags and Google Search Console integration. Performance is moderate, with potential improvements in loading speed and accessibility. No major technical debt or outdated libraries were detected, but security headers and analytics integration are missing.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
